I need to attach a 2x2 gatepost, with a flange at the bottom, to my 4"
concrete sidewalk.

What is the best way of bolting the flange (4 holes) to the concrete? I have
a 1/2" hammer drill with a 9/16" concrete drill bit.

How do I proceed from here? Can I just drill 4 holes in the concrete with
my 9/16 bit and then insert some kind of a fastener in the holes? What kind?

Do a Google search for "Concrete Sleeve Anchor". I've always had good
luck with them. Careful not to overtighten, however. You can snap
them with a breaker bar.
